Even if there are 0g of trans fat listed on the nutrition label, it does not mean that there is no trans fat in the product. Legally, companies are allowed to state that a product contains no trans-fats if it contains less than 0.5g, which is still trans fat!

Trans fats may be labelled as hydrogenated oil or partially hydrogenated oil, and they can be in anything from vegetable oil to palm oil, depending on how those oils have been processed.
